Schizo-Epistemology: Necessary and (False or Vacuous) [corrected]
Focus! Professor.
you seem to be somewhat obsessed with my opinion of Hume; but, the
argument I presented yesterday under this same subject line raises a
completely new question that has nothing to do with Hume. I’m reposting
a corrected version; the original had a serious typo that would have
changed its meaning.
try to remember that anyone might this question. would you refuse to
reply to everyone because you feel I have ignored your post about Hume?
[begin repost]:
Professor Crifasi,
one of your crucial claims seems to be that the proposition ‘I remain
self-identical throughout all my perceptions’ is a necessary condition
of existence.
this proposition may be symbolized, as follows:
[1]: P -> Q
where
P = ‘I exist’ [where ‘I exist’ = ‘I am not nothing’]
Q = ‘I remain self-identical throughout all my perceptions’
you also claim that Q is false; so:
[2]: -Q
recently, you’ve argued that you’ve been misunderstood.
>>your argument for [1] seems to be that Q is undeniable.
>I have never said that Q is undeniable. I have only argued that it is a
>necessary implication of self-existence.
yes; but, you also say that Q is false; and, you haven’t yet come to
grips with the oddity of having a primary premise, [1] above, that is a
conditional statement whose consequent is false.
if the consequent of a condition is false; then, the truth value of the
conditional as a whole depends on the truth value of the antecedent –
in this case ‘I exist’.
if the antecedent ‘I exist’ is True then conditonal is False
if the antecedent ‘I exist’ is False then conditonal is Vacuously True.
thus, Professor, your defense of Heidegger is based a premise that can
only be false or vacuous.
